    Self-organization in the 3:2:1 defense in handball: Behaviors from the complex dynamic systems
    (2024) Espoz-Lazo, Sebastián; Farias Valenzuela, Claudio; del Val Martín, Pablo; Hinojosa-Torres, Claudio
    This study aimed to describe collective emerging behaviors within a 3:2:1 defense training method in handball using the framework of complex dynamic systems. An observational methodology grounded in nonlinear pedagogy was employed, applying constraints to trigger defensive behaviors in response to offensive actions. Twelve players were divided into three groups for participation. The results revealed that emergent defensive behaviors were related to executed offensive actions during the exercise. Offensive ball-circulation actions consistently activated defensive responses aimed at maintaining the defensive structure, while offensive actions involving width and depth crosses prompted position changes, adjustments, and defensive contacts. Furthermore, spontaneous coordination among players was observed to self-organize and adapt defensive responses during the exercise. In conclusion, the nonlinear pedagogy approach rooted in complex dynamic systems was effective in fostering defensive responses in the 3:2:1 defensive system in handball.

    Transforming defensive teaching in handball: An analysis of applied constraints
    (2024) Espoz-Lazo, Sebastián; Reyes Contreras, Víctor; del Val Martín, Pablo; Hinojosa-Torres, Claudio; Farias Valenzuela, Claudio
    In the emerging field of sports science, the application of complex dynamic systems theory has opened new perspectives for understanding and improving sports training processes. Particularly in handball, a discipline that requires significant tactical coordination and adaptation, these concepts are ripe for exploration. The aim of this study was to investigate the influence of imposed constraints on defensive efficacy, demonstrating the relationship between defensive disposition and defensive actions in young handball players. The defensive actions of 12 young players were analyzed using a quantitative and observational approach, highlighting the influence of game constraints on tactical and technical formation. The results showed a significant relationship between defensive disposition and defensive actions, underscoring the importance of self-organization and adaptability in the training of young handball players. It reveals that variations in defensive strategies are influenced by imposed constraints, affe
